Knowledge graph construction and maintenance process:design challenges for industrial maintenance support

Abstract Knowledge graphs (KGs) structure knowledge to develop intelligent systems in several application domains. Industrial maintenance support requires knowledge and expertise on a variety of aspects of the factory, machinery, and components. However, the actual creation and maintenance process of KGs has remained unelaborated. We review the KG literature to integrate previous models into one process model also incorporating knowledge engineering principles within. The literature review and a subsequent case study together represent the problem and objectives definition phases of a design science project. The contributions include the integrated process model for KG creation and maintenance and the initially observed design challenges in the KG process operationalisation in a context of supporting industrial maintenance

Design objectives for evolvable knowledge graphs

Abstract Knowledge graphs (KGs) structure knowledge to enable the development of intelligent systems across several application domains. In industrial maintenance, comprehensive knowledge of the factory, machinery, and components is indispensable. This study defines the objectives for evolvable KGs, building upon our prior research, where we initially identified the problem in industrial maintenance. Our contributions include two main aspects: firstly, the categorization of learning within the KG construction process and the identification of design objectives for the KG process focusing on supporting industrial maintenance. The categorization highlights the specific requirements for KG design, emphasizing the importance of planning for maintenance and reuse

Application system design:maintenance

Abstract In this chapter the use of Arrowhead Framework is tested in two application environments. The first part of the chapter “Widening the scope: Managing maintenance data in large multifunctional plant environments” reports the challenges in the mining industry and how the challenges of this type of industry can be addressed with the Arrowhead Framework. The second part of the chapter “Aircraft Maintenance System” is from commercial aviation focusing on various examples related to maintenance
